Patented June 3, 1930 PATENT WILLIAM ALBERT FIFIELD,OF ABBEY, SASKATCHEWAN, CANADA SHOCKER Application filed August 14, 1928. 'SeriaI No. 299,478.

This invention is an attachment for self binders by the use of which the bundles as they are delivered from the binder deck will be gathered into a shock and delivered onto '5 the ground, the operation of the apparatus being to a great degree automatic and driven from the driving mechanism of the reaper and binder. The invention provides mechanism whereby the bundles will be sustained in an elevated position until enough bundles to form a shock have been delivered and will then be set on end in shock form and mechanically deposited in a row or line across the field parallel with the line of travel of the machine. The invention also provides novel mechanism whereby the moving parts will be accurately operated to accomplish the desired results. The invention is illustrated in the accompanying drawings and consists in certain novel features which will be hereinafter first fully described and then more particularly defined in the appended claims.

In the drawings:

Figure 1 is a plan view of a shock-forming mechanism embodying the invention;

Fig. 2 is a vertical section on the line 22 of Fig. 1 showing the bundle supports in the raised position;

Fig. 3 is a similar view showing the bundles delivered onto the platform to form a shock and in position to be discharged onto the ground;

Fig. 4 is a bottom plan View;

- Fig. 5 is a horizontal section on the line 55 of Fig. 3 looking in the direction inclicated by the arrows Figs. 6 and 7 are enlarged detail views of the mechanism for reversing the upper deck or bundle supports preliminary to the gathering of the bundles into a shock.

In carrying out the invention, there is provided a platform 1 which is preferably circular and is attached to the binder deck, a

portion of which is indicated at 2, the connection of the platform to the binder deck being preferably in the form of hinges, indicated at 8, and the outer edge of the deck being supported by a roller l adapted to run upon the ground in an obvious manner. It will 0 be understood that the construction and operation of the binder do not form parts of the present invention and hence the binder is not illustrated in detail in the accompanying drawings, although a portion of the edge of the binder deck has been shown in order that the relation of the shocker t0 the harvester will be understood.

At intervals around the center of the platform 1, legs 5 are secured thereto which extend upwardly in converging relation, as will be understood upon reference to Figs. 2 and 3, and upon the upper ends of these legs is secured a base plate 6 constituting the lower member of a housing which is completed by the provisions of a turntable or cover 7. Again referring to Figs. 2 and 3 more particularly, it will be noted that the base plate 6 is provided adjacent its edge with an upstanding annular flange or rib 8 and the cover or turntable is provided with a depending annular wall 9 which encircles said rib or flange and has its lower edge resting rotatably upon the base plate. The turntable is provided centrally with a hub member 10 encircling and rotatable about a post 11 which is secured firmly in the base 6 at the center thereof and rises through the hub 10, as clearly shown. The post is provided with an annular shoulder 12 resting upon the cover to hold the same in operative relation to the base and rotatably fitted upon the post above said shoulder is the hub 13 of a lever 1& which extends radially outward and has its free end pivotally attached to a pitman 15 extending to the binder deck and fitted upon a wrist pin 16 upon a crank disk or gear 17 which is driven from the operating mechanism of the binder. On the upper side of the cover is an annular ratchet 18 and pivoted upon the lever 14 is a pawl 19 which depends from the lever to engage in said ratchet, as will be understood. The gearing which actuates the pitman 15 is so proportioned and timed that it will operate in consonance with the delivery of the bundles and the lever 14 will be turned through an are equal to one-eighth of the circle defined by the ratchet 18, consequently rotating the cover through one-eighth of a circle at each operation. It will also be understood that the cover is thus operated in a step by step manner, the pawl engaging the ratchet upon its forward stroke and moving idly over the ratchet upon its return stroke. The hub 10 is provided in its outer circumference with equi-distant sockets to receive the inner ends of bundle-carrying arms 20 which pass through openings provided therefor in the wall 9 of the cover and may rotate therein. Adjacent the inner extremity of each arm 20, a beveled pinion 21 is secured thereon and all said pinions mesh with a gear ring 22 loosely fitted upon the post 11 and against the under side of the top of the cover. Adjacentthe pinion 21 on one of the arms 20 is a mutilated pinion 23 which, as shown most clearly in Figs. 6 and 7, has diametrically opposite blank portions and diametrically opposite tooth port-ions which alternate with the blank portions, and at one point upon the base 6 a short rack 24 is secured thereon in the path of the mutilated pinion whereby at the end of each complete revolution of the cover the mutilated pinion will operatively engage and be actuated by the rack to turn the arms 20 through one-half a revolution. Upon the outer portions of the several arms 20 are secured troughs or bundle carriers 25, there being two troughs carried by each arm and being disposed diametrically opposite each other so that the bundles may be received on the upper sides of the arms and when the arms are reversed to discharge the bundles there from a second set of troughs or bundle receivers will be presented in position to receive a second supply of bundles. The bundles are delivered to the troughs or receivers 25 by an endless conveyer 26 mounted upon the binder deck to receive the bundles as they are discharged from the binding devices and, as shown in Fig. 1, this conveyer extends over the shocker in such position that its outer bight is immediately adjacent the normal position of a bundle receiver and will deliver a bundle into the same. It will be understood that the step by step rotation of the turntable or cover 7 and the arms 20 is timed so that a bundle will reach the delivery point of the conveyer at the same time that a receiver assumes its position to receive the bundle. The bundle is delivered into a receiver during the period of rest of the turntable and during the succeeding rotation of the turntable the bundle is carried from the conveyer and a succeeding receiver brought into position at the delivery point of the conveyer. Inasmuch as the gear ring 22 is loose and rests by its weight on and meshes with all the pinions 21, the pinions will not rotate but will simply be carried around bodily with the gear ring. When eight bundles, however, have been deposited on the respective receivers and the turntable has completed one revolution the mutilated pinion 23 will be brought into mesh with the stationary rack 24 and the continued travel of the turntable will thereby cause said pinion to rotate and thereupon the meshing of the gear ring with all the pinions 21 will cause all the arms 20 to be rotated simultaneously, and the proportions of the gear portions of the mutilated pinions and the racks are such that the arms will be turned through one-half of a revolution.

Arranged to cooperate with the bundlereceiving and carrying troughs 25 are a plurality of lower troughs 27 which are equidistantly spaced around the device and are of the same semi-circular formation. These lower troughs 27 are each provided on the outer or under side with a longitudinal rib 28 which serves to reinforce the trough and has its outer end pivoted to a rocking arm or lever 29 and its inner end pivotally attached to a ring 30 which connects the troughs so that they will operate simultaneously in the action of the apparatus. The rocking arms or levers 29 are fulcrumed at or near their lower ends upon the upper side of the platform 1 and their lower ends may extend through radial slots 31 provided therefor in the platform, it being noted that only the alternate levers 29 are shown extending through the platform while the other arms 29 are pivoted at their lower ends upon the platform, and it may be also further noted that the platform is provided at one point in its edge, which will be the rearmost point in the direction of travel of the platform when the apparatus is in use, with a recess or opening 32 through which the shock may be discharged. The rocking arm or support 29 which is located at the said opening is in the form of an arch spanning the opening so that it will not interfere with the discharge of the shock. To the lower extremity of each of the longer arms or levers 39 is pivoted the outer end of a pitman 33, the inner end of which is connected to an eccentric strap 34 fitted upon an eccentric 35 which is mounted upon a shaft 36 suitably supported by and depending from the platform at the center of the same, and it will be observed upon reference to Fig. 4 that the several eccentrics are arranged at angles of ninety degrees with each other in order to obtain the proper simultaneous oscillation of the levers 29 actuated thereby. Secured to the shaft 36 above the uppermost eccentric 35 is a beveled gear 37 which meshes with a beveled pinion 38 on the end of a shaft 39 supported on the under side of the platform and driven in proper timed relation to the other parts by the mechanism of the binder.

Normally the troughs or bundle receivers 27 are in the raised position shown in Fig. 2 below the plane of the several arms 20, and it will be noted that the ribs 28 are so formed that some of the troughs or receivers 27 will set higher than others or in stepped relation. When the arms 20 are reversed, as previously described, the bundles supported by said arms will be turned over into the respective troughs 27, whereupon the arms 29 will be rocked so that the ring 30 and the inner ends of the troughs 27 will swing downwardly to the position shown in Fig. 3, thereby bringing the several bundles together to form a shock resting upon the platform at the center of the same. It may be here noted that the bundles are delivered from the conveyer 26 with their heads disposed outwardly with respect to the center of the platform and the ost 11 and, consequently, when the troughs 2 are swung downwardly to the position shown in Fig. 8, the bundles will be set on their butt ends with their heads uppermost and will be brought into compact relation to form a shock. The motion of the parts is so timed that the downward movement of the ring 30 and the connected bundle receivers will occur immediately after the turntable 7 has completed one revolution and discharged the bundles into the receivers 27 and the ring will not remain in its lowered position but will immediately return to the upper position shown in Fig. 2, thereby leaving the shock standing upon the platform in position to be discharged. The stepped relation of the bundle-receiving troughs 27 brings the bundles into compact form in the shock instead of being set in one circle.

To discharge the shock, I provide a pusher comprising an arcuate band 40 which will preferably extend through a semi-circle so that it will pass halfway around the shock. This band is disposed near the platform 1 and carried by the outer end of a piston rod 41 extending from a piston 42 working in a cylinder 43 carried upon the platform. The piston 42 is driven by fluid pressure admitted to the cylinder through pipes 44 leading from a suitable pump or compressor upon the harvester, and the controlling mechanism will be equipped with suitable valves whereby to control the direction of flow of the pressure fluid and effect return of the pusher after a bundle has been discharged.

.At the inner side of the outlet opening 32 in the platform, a cradle 45 is pivotally mounted on the under side of the platform and said cradle comprises a plurality of parallel fingers or light rods secured to a hinge bar or head 45 and extending outwardly beyond the edge of the platform. A bail or crank 47 is mounted in suitable bearings on the under side of the platform to extend across the opening 82 immediately below the cradle and normally support the cradle in its raised position, as shown in Figs. 2 and 3. One side of this bail or crank is connected through a rock'shaft 48 with a lever or pedal upon the binder whereby the operator may rock the bail or crank at will to permit the cradle to swing downwardly and thereby discharge the shock which has been moved over onto the cradle by the act-ion of the pusher. The cradle may, of course, be caused to dump the shock at the will of the operator and the shocks may thereby be deposited at such intervals or at such points as may be deemed most convenient or desirable. Of course, return movement of the crank or bail 47 will restore the cradle to its upper shocksupporting position.

If desired, spurs 50 may be provided in the several bundle-receiving troughs to hold the bundles against slipping and premature discharge as they are turned to upright position.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided an exceedingly simple and compact mechanism whereby bundles may be gathered into a shock and the shock deposited on the ground with a minimum expenditure of manual labor. The mechanism controlling the pusher may be arranged to operate automatically in timed relation to the deposit ofthe bundles in the form of a shock upon the platform so that the only operation required to be performed by the attendant will be that of tripping the cradle to deposit the shock on the ground. The working mechanism is compactly arranged and is so disposed that it is efiectually protected against chance blows and is, therefore, not apt to be damaged or put out of order by accident. The hinge connection of the platform with the binder deck will permit the platform to accommodate itself to unevennesses in the surface of the field and the travel of the apparatus over the field will not interfere in any way with the deposit of the shocks on the ground but, on the contrary, will facilitate such deposit.
